Effect Of Milk On Fibronectin And Collagen Type I Binding To Staphylococcus Aureus And Coagulase-Negative Staphylococci Isolated From Bovine Mastitis, J. Miedzobrodzki, A. S. Naidu, J. L. Watts, Pawel Ciborowski, K. Palm
Nebraska Center for Virology: Faculty Publications
Tryptic soy broth (TSB)-grown cells of Staphylococcus aureus isolated from acute and chronic bovine mastitis bound mainly 125I-fibronectin (125I-Fn), whereas strains of nine species of coagulase-negative staphylococci showed a predominant interaction with 125I-collagen (125I-Cn) type I. A particle agglutination assay (PAA) was used to examine the interaction of coagulase-negative staphylococci with 1251-Fn and 125I-Cn immobilized on latex. All 368 coagulase-negative staphylococci demonstrated high 125I-Cn and moderate to low 125I-Fn interactions in the PAA. Cn-PAA reactivity was high among strains of Staphylococcus xylosus (84.2%), Staphylococcus simulans (77.8%), Staphylococcus epidermidis (76.7%), and …

A New Species Of Moranida Mansell From Venezuela (Neuroptera: Nemopteridae), Robert B. Miller, Lionel A. Stange
A New Species Of Moranida Mansell From Venezuela (Neuroptera: Nemopteridae), Robert B. Miller, Lionel A. Stange
Insecta Mundi
Mansell (1983) described two new species and genera of Crocinae from Peru and Bolivia bringing the total number of South American species of this subfamily to five species. However, all five species occur well south of the equator. Recently the authors discovered a sixth species in northern Venezuela greatly extending the northern range of the family in South America. This new species belongs to the genus Moranida Mansell. Both adults and larvae were found and are described here with a key to the species of Crocinae of South America. We also found and reared Moranida peruviensis Mansell from Lambayeque, Peru, …

Book Review: Larvas De Coleoptera Do Brasil By Cleide Costa, Sergio A. Vanin, And Sonia A. Casari-Chan, P. Jolivet
Insecta Mundi
This is a remarkable new book which is certainly well above all that has been done up to now in this field. Moreover, it deals with a fauna on which we have very few biological data. One hundred nine beetle families are reviewed, from the curious Micromalthidae to the Curculionidae. Mrs. Costa showed me the proofs of the book in 1987 in Sao Paulo, and I had the opportunity then to admire the good quality and even perfection of the drawings.
Book Review: Biologie Des Coleopteres By Renaud Paulian, P. Jolivet
Book Review: Biologie Des Coleopteres By Renaud Paulian, P. Jolivet
Insecta Mundi
This entirely new book is the first on the biology of beetles since Crowson's book, published in 1981 by Academic Press. This new work in some ways completes Crowson's, but in no way is it a useless repetition. The two books together give a good idea of the biology of this enormous order, here comprising more than 200 families. Paulian's classification is slightly, but not fundamentally, different from Crowson's. There are excellent chapters on endogeous, caverniculous, aquatic, coprophagous, termitophilous, and myrmecophilous beetles. Termitophilous beetles have already been treated well in Termitologia by Grasse (1986, Masson, Paris). Paulian is a well-known …

Identification And Nesting Sites Of North American Species Of Dolichoderus Lund (Hymenoptera: Formicidae), Clifford Johnson
Identification And Nesting Sites Of North American Species Of Dolichoderus Lund (Hymenoptera: Formicidae), Clifford Johnson
Insecta Mundi
The identification of North American Dolichoderus species by-way-of existing keys is unnecessarily arbitrary and misdeterminations are likely between D. mariae and D. pustulatus, the latter species showing most morphological variation over its range. Diagnoses for the four described species and an undescribed form with a revised key and figures are given to aid entomologists working without identified voucher specimens. Nest data for species other than D. pustulatus in the Coastal Plain revealed below-ground nests or structures immediately at the ground sui-face. Colonies of D. pustulatus in Florida and southern Georgia have arboreal nests in the cavities of smaller limbs …

Impairment Of Melibiose Utilization In Streptococcus Mutans Serotype C Gtfa Mutants, Raul G. Barletta, Roy Curtiss Iii
Impairment Of Melibiose Utilization In Streptococcus Mutans Serotype C Gtfa Mutants, Raul G. Barletta, Roy Curtiss Iii
School of Veterinary and Biomedical Sciences: Faculty Publications
The Streptococcus mutans serotype c gtfA gene encodes a 55-kilodalton sucrose-hydrolyzing enzyme. Analysis of S. mutans gtfA mutants revealed that the mutant strains were specifically impaired in the ability to use melibiose as a sole carbon source. S. mutans gafA mutant strains synthesized less α-galactosidase activity inducible by raffinose than wild-type strains. Melibiose (an inducer in wild-type strains) failed to induce significant levels of a-galactosidase in the mutant strains. We hypothesize that melibiose use by . mutans requires the interaction of the GtfA enzyme, or another gene product under the control of the gtfA promoter, with other gene product(s) involved …
Bradyrhizobium Japonicum Survival In And Soybean Inoculation With Fluid Gels, Michael D. Jawson, Alan J. Franzluebbers, Robert K. Berg
Bradyrhizobium Japonicum Survival In And Soybean Inoculation With Fluid Gels, Michael D. Jawson, Alan J. Franzluebbers, Robert K. Berg
Department of Agronomy and Horticulture: Faculty Publications
The utilization of gels, which are used for fluid drilling of seeds, as carriers of Bradyrhizobium japonicum for soybean (Glycine max (L.) Merr.) inoculation was studied. Gels of various chemical composition (magnesium silicate, potassium acrylate-acrylamide, grafted starch, and hydroxyethyl cellulose) were used, although the hydroxyethyl cellulose gels were more extensively investigated. Gel inocula were prepared by mixing gel powder with liquid cultures of B. japonicum (2% [wt/vol]). The population of B. japonicum USDA 110 did not change in each gel type during 8 days of incubation at 28°C. These fluid gels were prepared with late-exponential-growth-phase cells that were washed …
Management Strategies To Minimize And Reduce Soil Compaction, A. J. Jones, R. A. Wiese, Elbert C. Dickey
Management Strategies To Minimize And Reduce Soil Compaction, A. J. Jones, R. A. Wiese, Elbert C. Dickey
Department of Agricultural and Biological Systems Engineering: Faculty Publications
Nature has some built-in processes that reduce soil compaction. They include cycles of wetting and drying, and freezing and thawing.
In the last 20 to 30 years, farming practices have changed drastically. These farming changes have made it more difficult for nature to rejuvenate the soil environment to an optimum condition for crops. Performing field operations on wet soils, using multiple field operations to grow the same crop continuously, and eliminating meadow crops from crop rotations contribute to more extensive and deeper compaction.
Each farmer has the opportunity to make decisions that can keep soils from becoming compacted.

Great Plains Wildlife Damage Control Workshop Proceedings
The effectiveness of monofilament line, reflective tape, beach-balls and pyrotechnics (propane cannons and shotgun scare shells) in reducing damage to citrus by great-tailed grackles was tested in the lower Rio Grande Valley of southern Texas. Results indicate that these treatments can produce reduction in damage. Whether the treatments are economically advisable for a grower depends on the history of grackle damage to the grove and grove size. Only large amounts of damage in large groves justify costs associated with implementation of these methods.
Fall Food Habits Of Double-Crested Cormorants In Arkansas, Albert E. Bivings, Michael D. Hoy, Jeffrey W. Jones
Fall Food Habits Of Double-Crested Cormorants In Arkansas, Albert E. Bivings, Michael D. Hoy, Jeffrey W. Jones
Great Plains Wildlife Damage Control Workshop Proceedings
One hundred forty-eight double-crested cormorants (Phalacrocorax auritus) were collected in October-December 1988. Some were collected while actively feeding, but most were collected at loafing or roosting areas. Of the 135 with fish in them, 79% contained gizzard shad (Dorosoma cepedianum) and 16% contained centrarchids (mostly Lepomus sp.). The rest contained a variety of aquaculture (commercially raised) fish. Fish prey weights were estimated from total length of prey items and use of published length-weight tables. Total weights of prey ranged from 39 to 4558 with a mean of 185g. This was felt to be a conservative estimate …
Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans
Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans
Great Plains Wildlife Damage Control Workshop Proceedings
We compared the potential of Alpha-chloralose (A-C) and DRC-1339 to reduce a nesting population of herring gulls at an industrial site in Ohio in 1988. Almost all treated baits were consumed by gulls but only about one affected gull was noted for every 10 baits consumed of either chemical. A test indicated our DRC-1339 baits. containing 3.7 - 7.4 times the published LD value, were not lethal to most captive herring gulls living in fresh water. LD values of A-C and DRC-1339 need to be more precisely estimated for gull species in fresh and salt water environments.
Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson
Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson
Great Plains Wildlife Damage Control Workshop Proceedings
In Kansas prairie dog management is primarily determined by private individuals and local government agencies. We conducted a mail survey of 350 affected landowners as a means to evaluate the effectiveness of current prairie dog control. The same survey was also sent to 350 randomly selected state residents within the general prairie dog range. We evaluated people's perceptions of prairie dogs, the effectiveness of control methods, costs of control, and reasons for poor response to control techniques. Results indicate people that have previously been involved in prairie dog control on lands they manage have different opinions about prairie dogs than …
Trophy Game Animal Damage In Wyoming, Ron Iversons
Trophy Game Animal Damage In Wyoming, Ron Iversons
Great Plains Wildlife Damage Control Workshop Proceedings
Wyoming is perhaps one of the most liberal and unique states of the fifty states on compensation for game and trophy game animal damage. Trophy game animals as defined by statute in Wyoming includes the Cougar (Mt. Lion), Black Bear, and the Grizzly Bear. According to statute Wyoming is responsible for damages incurred by these species to livestock, land, crops, improvements, and extraordinary grasses. Since the statutes were enacted Wyoming has been faced with a variety of complaints and damage claims caused by these species. Damage complaints received by the Department have covered a broad spectrum, ranging from the stockman …
Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores
Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores
Great Plains Wildlife Damage Control Workshop Proceedings
Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning dove, white-winged dove, and great-tailed grackle in significant numbers. Nesting success was not reduced significantly by any treatment but observations indicate that cannon treatments are likely to have a negative impact on overall nesting success for several species.

Emphasis is placed on planning and risk analysis. Four levels of planning have been identified: (1) strategic planning for the Agency, (2) strategic planning for each of the 11 units, (3) program design and risk analysis, and (4) operational planning.
Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios
Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios
Great Plains Wildlife Damage Control Workshop Proceedings
Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …

Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway
Great Plains Wildlife Damage Control Workshop Proceedings
Arizona has experienced an increase in urbanization of wildlife habitat, which has led to an urban nuisance wildlife problem. The Arizona Game and Fish Department is working to lessen the problem through public education, information packets and use of private pest control companies to remove wildlife for a fee.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth
Great Plains Wildlife Damage Control Workshop Proceedings
Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Diversity Of Coprophagous Scarabaeidae (Coleoptera) In Grazed Versus Ungrazed Sandhills Prairie In Western Nebraska, Mary Liz Jameson
Diversity Of Coprophagous Scarabaeidae (Coleoptera) In Grazed Versus Ungrazed Sandhills Prairie In Western Nebraska, Mary Liz Jameson
University of Nebraska State Museum: Entomology Papers
Baited pitfall traps were used to compare the dung-feeding Scarabaeidae (Coleoptera) of a grazed versus an ungrazed sandhills prairie in western Nebraska. Traps yielded 14,832 coprophagous Scarabaeidae over a 4-week sampling period in 1987. Canthon ebenus (Say), C. pilurarius (L.), Onthophagous hecate Panzer, and O. pennsylvanicus Harold were the dominant species on both prairies. The Shannon-Wiener diversity index indicated that diversity was slightly higher on the grazed site, whereas the Margalef diversity index showed the diversities to be nearly the same. Activity and foraging by scarabs (as measured by trapping success) were found to be most closely correlated with temperature …

Evaluation Of Irrigation Planning Decisions, Derrel L. Martin, James R. Gilley, Raymond J. Supalla
Department of Agricultural and Biological Systems Engineering: Faculty Publications
A method is developed to determine optimal irrigation strategies for a single season using crop production functions which incorporate physically based coefficients. The relationship of yield to evapotranspiration is used to develop the yield-irrigation function. The physical parameters used in the production function can be determined from field measurements or various types of computer simulation. Using this approach, the optimal irrigated area and depth of water to apply can be related to prices, costs, and physical parameters. This produces a more general solution than commonly used production functions that depend on limited experimental results. The optimal irrigation depth and irrigated …

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaiusp hoeniceus) and Common Grackle (Ouiscalus auiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …
